Description
Technical field
A kind of miner set cable anti-slip protective device of the utility model belongs to miner set cable anti-slip guarantor
Protection unit technical field.
Background technique
Since the terrain environment of working face in the pit is complicated, during coalcutter moves forward coal cutting, the roof collapse stone of coalcutter
The phenomenon that head, carbon block stumble crawler belt happens occasionally, and working face is latched every ten pack support and installs one, as the work people of nurse crawler belt
Member sees that need to go to coalcutter locking place from bracket front end after crawler belt stumbles is latched equipment.
Since crawler belt work is during being latched coalcutter, unit is also moved forward in traction crawler belt, and equipment is not
It can be latched at once, gently then damage unit crawler belt, pipeline in crawler belt in the process, drag arm etc., it is heavy then cause cable phase
Between the failures such as short circuit, single-phase earthing, electric leakage generation, and then cause cable phase fault, burn binding post, damage control loop
Etc. accidents generation, seriously affect production run, there are biggish security risks.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, technical problem to be solved are as follows: provide one kind
Miner set cable anti-slip protective device；In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows:
A kind of miner set cable anti-slip protective device, including unit electric control protection device, in the unit electric control protection device
The normally closed point of power supply be connected with the close point control terminal of limit switch；
Mechanical linkage on the limit switch unit cable core intracavitary with unit switch wire connection is arranged in is connected；
The limit switch is arranged on the intracavitary fixed point of unit switch wire connection；
The model AZ8-104 of the limit switch.
What the utility model had compared with the existing technology has the beneficial effect that the utility model is mainly used in underground coal mine
The protection of coal mining machine in full-mechanized mining face cable anti-slip, frequently encounters spoil in cable trough, carbon block or electricity during coalcutter coal cutting
Cable slot guardrail card mixes cable, and cable is caused to pull or damage, and electric cable for coal mining machine can be effectively prevented, electricity occurs when card is mixed
Cable pulls impaired accident；The utility model structure is simple, easy for installation, at low cost, is suitble to pacify in all coalcutter systems
Dress uses.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1 being unit electric control protection device, 2 be limit switch, 3 be unit cable core.
Specific embodiment
As shown in Figure 1, a kind of miner set cable anti-slip protective device of the utility model, including the automatically controlled protection of unit
Device 1, the normally closed point of power supply in the unit electric control protection device 1 are connected with the close point control terminal of limit switch 2；
Mechanical linkage on the limit switch 2 unit cable core 3 intracavitary with unit switch wire connection is arranged in is connected；
The limit switch 2 is arranged on the intracavitary fixed point of unit switch wire connection；
The model AZ8-104 of the limit switch 2.
The utility model acts to prevent working face cable from pulling or damaging when card is mixed by setting limit switch,
In use, driving limit switch 2 that its normally closed point is made to disconnect and be latched unit when unit cable core stress pulls, making whole
A compressor emergency shutdown；The utility model is for the disadvantage existing for unit, in conjunction with reality of work and sufficiently on the basis of investigation, in unit
Switch wire connection one limit switch of intracavitary installation, once unit cable core 3 is subjected to displacement painstakingly by dragging, limit switch 2
It can be latched the control loop of unit electric control protection device 1 rapidly, power-off parking is realized to unit.
Limit switch 2 is also known as travel switch, and being fixed when use, to be mounted on unit switch wire connection intracavitary, by limit switch
Mechanical linkage and cable connection on 2, when cable is displaced by dragging, the connecting rod on limit switch 2 is acted, and disconnects limit
Close point in switch, the normally closed point in unit electric control protection device 1 disconnect, and control compressor emergency shutdown；Weight is needed after issue handling
When new booting, needs staff to open unit wire connection cavity and manually reset limit switch 2.
The real work of miner set has been tested using the utility model, has verified defencive function；During verifying
When miner set is run from head toward the coal cutting of tail direction to 171# frame, fallen between working face 83# frame and 84# frame frame one piece it is broken
Stone is just stuck in cable trough, and crawler belt work finds that reaching scene immediately after the hidden danger is excluded, due to rubble surface imperfection
Corner angle are more, cause crawler belt work that can not take out, at this time it has been found that the crawler belt of coalcutter stretching is painstaking, at this time staff prepare
Return is latched unit, and in return course, unit automatic blocking is simultaneously shut down；Discovery is checked by staff afterwards,
Entire unit cable, circuit, frequency converter are intact, find that the mechanical linkage of limit switch acts after opening unit wire connection cavity, and
After manual reset limit switch, normal boot-strap operates unit again, does not such as install the protective device, by cable bad or may incite somebody to action
Cable, which pulls, causes short circuit accident.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
